GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 389,757, datedSeptember 18, 1858. Application filed April 2, i987. Serial No. 233,443.(No modeLl Patented in England May 31, 1887. No. 7,885.

.To all whom it may concern:

Be it known that I, EUGNE MOREAU, a citizen of the Republic of France,residingat Philadelphia, in the county of Philadelphia 5 and State ofPennsylvania, have invented certain new and useful Improvements in Gas-Burners, (for which a patent in Great Britain, N o. 7,885, bearing dateMay 31, 1887, has been obtained,) and I do hereby declare thefollowing-'to be a full, clear, and exact description of thei.nvention,such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to that class of lamps wherein the heat of theproducts of combustion from the ame is imparted to the air-supply and tothe combustible gas for increasing the illuminating-power of the flame;and the nature thereof consists in certain improvements in theconstruction of burners of such lamps,w hereby a better combustion ofthe gas is obtained, the number of parts of which the burner is composedlessened, and the cleaning of the gas-passages facilitated.

In the lamp described in English Patent No. 14,335, of November, 1886,the burner which is screwed into the lower part of the gaschamberconsists of a tubeplate provided with a large number of holes forholding together the gas tubes, a series of tubes, each of which ispassed through the holes in the tube-plate, a ring to which the lowerends of the tubes are secured, and a stem supporting a dellectingbuttonwhichis screwed into the tube-plate.

My present invention is an improvement on the burner described in thesaid English patent; and its object is to simplify and render moreeconomical theconstruction ofthe burner, so that it may be finishedafter Ybeing cast entirely by drilling, turning, and milling machineryadapted to the purpose. According to my present invention, all theseparts are constructed of one and the same piece of metal by firstturning a casting to the required form,then drilling th rough the sameholes for the passage of gas, and nally cutting or milling air-spacesbetween the holes or bores. I also combine with the burner a centralreceptacle or chamber, for the reception of impurities, having a 5oremovable bottom.

In the accompanying drawings, in which l corresponding parts aredesignated by similar letters, Figure 1 represents the burner applied toa regenerative gas-lamp of known construction. Fig. 2 is a verticalsection showing the 55 burner detached from the lamp. Fig. 3 is asectional plan of the burner illustrated in Fig. 2. Fig. 4 is a verticalsection illustrating the improvements for preventing the deposit ofcarbon and facilitating the cleaning of the gas- 6o passages. Fig. 5 isa sectional plan of the burner illustrated in Fig. 4. Fig. 6 illustratesa burner the lower rim of which is provided Witha protecting device.Fig. 7 illustrates that part of the burner shown in Fig. 2 which is madein a single piece as it appears before the gas and air passages aredrilled or cut therein. Fig. 8 illustrates that part of the burner shownin Fig. 4 which is made in a single piece as it appears before the gasand air passages are drilled or cut therein.

In constructing the burner shown in Figs.` 2 and 3, the casting is firstturned in such a manner as to assume the form shown by the outerbounding-lines of Fig. 3, when the delecting-button is removed, thethreads upon the periphery and upon the lower part of the rod E beingcut in this operation, The requisite holes C-inthis instance twentyeight in number-are then drilled, and the requisite number of slots d-inthis instance twentyeight-are afterward milled between the holes orbores C from the annular rimD to the shoulder B, and also above theshoulder B to the top of the cylinder. The buttonFis then fastened uponthe stem, and the burner is coinpleted in two parts instead of the manywhich have been heretofore required. In the burner illustrated in Figs.4 and 5, the tube-cylinder, instead of extending above the plate orshoulder B, is provided with an inner annular beveled edge, C2,immediately under which is the recess or cup G, constructed in the formof an inverted cone, and provided with a downwardly-projecting tubularstem, E, the bore Vof which is closed by the button F. As the tubes Care cleaned by means of a wire driven through them,which forces thecarbon deposits upward, the beveled surface C prevents the accumulationof the carbon residue, and causes it to fall into the recess G below,from which it may be readily removed by unscrewing or ICO removing thebutton F from the hollow stem E. The lower annular terminal of theburner D is provided with small grooves H, (best shown in Fig. 5,) whichcompel the air flowing toward the llame to reach the gas at a point verynear its exit from the burner, and thereby greatly facilitate itscombustion.

In Fig. 6 a shield, J, is shown forprotecting the lowerauular terminalof the burner. This shield is of annular form,and is provided on itsouter and inner edges with ring-shaped flanges, which iit about theterminal annulus of the burner and protect it from the oxidizing ef feetof the hot gases. As the shield is removable, it may be readily replacedwhen it is worn out. which is made of a singlepieee ofmetalisillustrated as it appears before the gas-passages C are bored andthe air-passagesd milled therein.

Having thus described my invention,I claim and desire to secure byLetters Patentl. A gasburuer comprising an annular bottom, drilled holesfor the passage of gas, spaces between the gas-passages cnt or milled InFig. 7 that part of the burnerA out for the passage of air, and aprojecting ceptacle or chamber for the reception of impurities, aremovable bottom to the central chamber or receptacle, and aseries ofgas-pas sages surrounding the central chamber or receptacle, as and forthe purpose described.

3. In agas-buruer, the combination of acentral chamber or receptaclecommunicating with the gaspassages, having its upper end beveled at theentrance of the gas-passages, a tubular extension to the centralchamber, a button fastened to said extension, and a series ofgas-passages surrounding the tubular extension, as and for the purposedescribed.

'In testimony whereof I have aliixed my signature in presence of twowitnesses.

EUGENE MOREAU.
